invention relates to the mattress makmg art and has for its object to provide a novelmethod of finishing mattresses of a certain type to produce a very attractive and durable structure while eliminating expensive hand labor which is now incident to the production of so-called roll-edges along the corners of such structures. v 4 r My present invention relates in part particularly to that type of springfilled mattress shown and described in Letters Patent of the United States No. 1,700,339, dated January 29, 1929, and more directly to the specific form of that structure shown and described in my pending a plication for United States Letters Patent, erial No. 317 ,816, filed November 7, 1928, wherein top and bottom padded walls, including means for engaging the same with rows of interposed springs, are first made u then associated with the springs to provi e a structure open at sides and ends. p

This structure presents the problem of pro viding a cheap and eflicient means of or method for attaching the boxing strip to close the open sides and endsand, at the same time, produce an attractively finished structure which shall present roll-edges. The

mere attachment of an ordinary boxing strip is, of course, easy of accomplishment but it was found difficult to form an attractive upstanding roll-edge on or to otherwise so form the peripheral corners as to give the structure a very attractive appearance and also render it very strong and durable without greatly adding tothe expense of production.

The main object of the present invention is toprovide a method whereby the attachment of the boxin and formation of the roll-edges is 'accomplis ed by a single operation capable of being carried out by a sewin machine.

In order that the method 0 the present invention may be readily understood, reference is had to the accompanying drawings wherein:

While the invention has special reference to the particular type of mattress structure above referred to and illustrated in the ac companying drawings, I desire it to be understood that it ma be applied to other types of mattresses wit out departing from the invention as defined in the ap ended claims.

comprises top and bottom walls land 2, each", of which comprises two layers 3 and:4 of

burlapor other suitable fabric on one or} which lines aresuitably printed or otherwise applied which divide its surface into small square areas. In each of the latter, on the The mattress structure s own in Fig. .3

layer or sheet 4, there is provided a central opening'or a diagonal slot of less length than the diagonal of the area, these markings and slots being omitted from illustration.

The two layers 3 and 4 are then joined by lines of stitching extending longitudinally and transversely of said layers or sheets and following alternate lines impressed or 1mprinted on' the layer or sheet 4 so that said lines of stitching define areas each contalning four of the small square areas except along the edges and corners.

Padding, such as cotton, is then laid upon the layer or sheet 3, a cover fabric 5, such as ticking, laid upon the padding and said tlcking and padding then secured to'the two layers 3 and 4 by means of lines of stltching 6 and 7, which alternate with the first mentioned lines of stitching so that now all of the square areas of the layer 4 are bordered or defined by lines of stitching, the padding and ticking forming biscuits, eac of an area of four of the small square areas. The several fabrics 3, 4 and 5 and the layer of padding are of such width and length as to provide free peripheral edge portions 8.

The several lines of stitching above mentioned serve, conjointly with the fabrics 3 and 4, to provide square flat pockets which receive the end coils of the springs 9.

The above described structure and the method of making the same are fully illustrated and described in the above mentioned pending application but may be regarded as unimportant and not limiting the present invention to improvements in and upon that particular type-of structure as the only requisite of that or any other structure to which the present invention is applied is that it shall present free edge portion 8 peripherally of the top and bottom fabrics of a mattress structure which ma be spring-filled or may be filled with pa ding materials of any kind commonly used for mattress stufing.

While in the instance illustrated, the free edge portions 8 include several fabrics and interposed padding, which is preferable, I

desire it to be, understood that this is not essential to thelpresent invention as will hereinafter appear;

Upon completion of the mattress top and bottom walls of the casing and the association of the springs 9 therewith, the boxing strip is applied in the following manner.

A padded boxing'strip 10 is used. This, in the instance illustrated, consists of two strips 11 and 12 of suitable fabric between which is a layer of padding such as cotton, the strips 11 and 12 being joined by stitchchains 13 extending transversely of the longitudinal edges of the said strips and through the padding. These stitch-chains 13 may spaced from each other as desired and may be arranged in any other manner than that shown ,as their sole function for the purposes quilted boxing upon the body thereof as a shown in Fig. 4, to produce suflicient bulk to form a roll edge of ample cross-sectional" dimensions to produce a rounded or corner finish proportionate to the dimensions of the mattress body to render the whole mattressattractive.

The mattress body and quilted boxing strip 10 having been respectively roduced,= the next steps, which constitute t e essence of this invention, consist in folding .the free edge portions 8 of the top and bottom walls of the mattress bod upon themselves as shown in Fig. 4, then olding the longitudinal edge portions of the boxing strip lO-upon the. inner face of the body thereof as shown'in Fig. 4, then positioning the folded edge portion 8 and folded boxin strip .10 in the relation shown in Fig. 4, an then passing a stitchchain 14 through these respective folded elements to thus, in a single operation, attach one folded side edge portion of the boxing strip 10 to the top or bottom wall of the mattress body and thus form the roll-edge without resort to the further operation of inserting roll-edge ties such as have been heretofore necessary. Y

Incidentally this operation also forms a very attractive bead or piping 15 which lies just inwardly of theroll-edge of the boxing and renders the whole structure very attractive in appearance. This piping may include some of the padding of the ed e portions 8 or may be limited to a fold of the ticking only as the mattress maker may elect. i

It will be appreciated, of course, that 'the folding of the edge portion 8 and of the ed 6 portions of the boxing is done progressive around the mattress body immediatel in ad vance of the stitchin 14 which may, 0 course, be effected by hand t ough machine sewing is preferable because of greater speed, lower cost and neater appearance.

Obviously the folded edge portions joined by the stitch-chain 14 may be basted in advance of the stitching, if desired, though this has been found unnecessary in practice.

past to produce a quilted boxing ha'vin rolledges completed prior to attaching sai boxing to the mattress body but that method has not to my knowledge been used commercially as not constituti a practical solution of the problem of-obviatmg the hand labor incident,

to the formation of roll-edges on mattresses.

While the invention is particularly intended and adapted fdr the class of mattresses first above referred to-wherein the springs are so associated with the top and bottom walls of the structure as=to beheld in proper relative positions thereby, the'invention is alsovery 'andl.

The'boxing strip 21 is identical, preferably,

with that shown in Fig. 2, but may be of any other form ofquilted structure. This strip 21 is folded exactly as is the strip 10 of the structure of Figs. 1 to 5 inclusive and is preferably laid upon the bed plate of a-sewing machine with its folded edge portion uppermost. A peripheral free edge portion 22 of a topor" bottom wall is then placed in folded position as shown in Fig. 8 to overlie the folded edge portion of the boxing strip and the stitch-chain 23 then passed through the several folded elements to thus join the same and at the same time form the roll-edge 24 and the piping 25 of the mattress-casing as shown in Fi 6 and 9.

' After the boxing strip has thus been se: cured to the sides and one end of the top and bottom walls, leaving the portion 26 of said strip free, 'as shown'in Fig. 6, a spring assembly or other filler is inserted into the casing and the portion 26 of the boxing strip then secured in the manner described with referenceto the structure of Figs. 1 to 5, in-

clusive.

The structure resulting from the above described inethod as regards that shown in Figs. 1 to 5 and Figs. 6 to 9, constitutes an improved article of manufacture for reasons hereinabove set forth and is defined in some of the appended claims.
